SELF-HEATING SADIRON.

Application led .Tune 2, 1925. Serial No. 34,450.

To all whom t may concern: Be it known that I, Josnrn LSGHMIDT, a citizen of United States, residing at Blossvale, in the county of Oneida and State of New York,`have invented certain new and useful Improvements ink Self-I-Ieatingv Sadirons, of which the following is a specication, reference being had therein to the accompanying drawing.

My invention relates to aselflheating sad iron and I declare the following to be a full,

clear, concise and exact description thereof' sufcient to enable anyone skilled lin the art to which it appertains to make and use the same, reference being had t0 the accompanying drawings in which like reference char` acters refer to like Vparts throughout the specification. f'

The object of the invention is to provide a self-heating sad iron that can burn a com? bustible fuel such as` gasollne or kerosene.l

In such an iron there isl a pressure tank adaptedV to force the fuel through the burner in a sprayj;V The present invention is designed to vpermit'the user vto pump air fromA time to time as needed into the .pressure tank with one hand while ironing with the other. e

The object will be understood by referring to the drawings', in which:

Fig- 1 is a perspective view ofy the' device;v

' Fig. 2 is a central vertical section of the device; showing parts in full.

Fig. 3v is a detail perspective view of certain pipes;

`Fig'. 4 is; a' sectional v-iew somewhatl enlarged and taken o n vthe line 4, 4 of Fig. 3. vReferring more particularly to the drawings, the device embodies a hollow-casing 1 having a smooth nickel plated surface on the bottom adapted for ironing purposes.-

A coverplate '2 is attached-'by screws 3 to casing l. A burner tube 5 having a bendhat 6 is' screw'mounted atvone end toa casing 7 held by screw 8 to cover plate 2. Casing 7 is recessed at 9. A similar recess 10 being made to aline therewith in cover plate 2. The end of burner tube 5 opens into re-` cess 9 of casing 7 Directly opposite the location of the open end of` burner tube 5 is situated the end of another tube 12 having a cap 13 with a very line pin hole therein screw mounted thereto. Tube 12 extends rearwardly and is wound in a coil at 15. Coil 15 is located opposite an opening 16 made in the side wall 17 of casing 1. The

' inA said socket.

endof tube 12 is united in a permanent man-V ner to afpipe 20 having a branch pipe 21 disposed at an anglev thereto and opening into pipe 20. f Y

VA valve 22 is mounted in pipe 20'at the location of the junction of branch pipe. 21,

which valve is controlled byy astem 23 having .an annular handle 24 for turning said stem.v 4Agland or nut 25 ris screw threaded to the end of pipe 20'fto prevent leakage. C

Branch pipe 21 is connected by a tube `26 with the loweren'd of the sphericalshaped reservoir 27. A nut 28 isscrew mounted on the end 'of pipe 21 to prevent leakage at the junction. The'opposite endo'f tube 26 is enlarged at 29 andyscrew threaded for mounting to a corresponding socket formed inthe lower surface of reservoir 27. A nut 30 is 'employed' to lock the end of -tube`26 There is mounted also on enlarged part 29v an annular boss 31 having a serrated outer peripheral surface to aid in' turning thesame and a' vcentral screw threaded aperture for mounting ontheenlarged part 29 lof tube 26," whereby to hold inplace the bifurcated end `33 of bracket 34.

Vhand to work the flat iron. 'Handle 45 isl hollow for the reception of metal cylinder 46 containing a piston 47 -attached to ya pis.

ton rod 48 Vhaving anv annular vwooden or fabric handle 49 Aon the freek end thereof. Cylinder 46 isclosed at one end by metal member 50vhavin`g ad-isk part51 to fit the end of cylinder -46'and'a threaded extension 52. A11. aperture is made rthrough member.

50 for the sliding reception of piston rod 48. Disk part 51 is Xed to cylinder 46 by rivetes 53 or in any other suitable manner. The opposite end of cylinder 46 is closed by cap 55 having an aperture for screw mounting the end of tube 56. Cap 55 is brazed or otherwise secured in a permanent manner to cylinder 46.

Cylinder 46v is supported by the upper ends of U shaped bracket 35, which ends are equipped with holes for the projection of extension 52 of member 50 and tube 56 respectively.

Tube 56 is united by a union coupler 60 with another tube 61 that is attached to a cap 62 screw threaded to the corresponding threads of mouth member 63 of reservoir 27. Reservoir 27 yhasalso an inlet port 65 into which is poured the gasoline or other' liquid fuel lused. A cap `66 isscrew threaded to the mouth piece of port 65, whereby to close the same. A rubber or fabric gasket or disk 70 being disposed in `said cap 66 to make an air tight fit.

The operation of the invention is effected by pouring gasoline into reservoir 27 through 4port 65 until the same is nearly filled and by then pumping air into vreser- Voir 27 by meansof pump handle 49. An alcohol vtorch notshown, is then thrust into casing 1 through opening 16 made in wall 17 :and ignited, whereby to act as a burner totheat coil 15of tube 12 and thereby Vapor-- izing the 4fuel that has been admitted yto tube 12, valve '22 having been opened in the meantime. The Vaporized gasoline will be forced by Vthe pressure `created in reservoir 27through tube v26 to branch pipe 21 to--tube 12 and out throughcap `13 towardsopening 16 lin burner tube 5. `As the fuel is forced across the recess 10 into burner tube 5 air will be sucked 4along therewith to further vaporize the fuel which will be ignited as it comes out of the narrow slots formed on the `under side of Vburner ytube 5and along the upper surface of the'bottom partof casing 1, whereby to heat the same :for ironing` purposes. As the fuel diminishes in reservoir 27 vand the pressure thereby grows less, the pressure may be increased from time to time by actuating .pump or piston handle 49 with one hand while still ironing with the other.

Havingthus described my invention what I claim as new and desire to secure by Letters Patent is:
